◆ CalculateNodeCoordinateSystem()

	)		const

protectedinherited

This function will calculate the Tangent and Up vectors automatically to sensible values without user input for the parent nodes within the current yarn. It may be desirable to give more control to the user.

◆ Copy()

CInterpolation * TexGen::CInterpolationBezier::Copy ( ) const

inlinevirtual

This is a function to allow copying of derived classes correctly.

Derived classes should implement this as CInterpolation* Copy() const { return new CInterpolationDerived(*this); } where CInterpolationDerived should be replaced by the name of the derived class

Implements TexGen::CInterpolation.
